Stabilizing Perovskite Structures by Tuning Tolerance Factor: Formation of Formamidinium and Cesium Lead Iodide Solid-State Alloys
Zhen Li†, Mengjin Yang†, Ji-Sang Park†, Su-Huai Wei†§, Joseph J. Berry†, and Kai Zhu*† / This is an " an outstanding piece of work that applies fundamentals of solid state science to understand the source of instability of these materials: The central importance of the tolerance factor, as described in this paper, enables the tailoring of the stability of the lead-halide perovskites through solid state alloying, thus providing a critical insight to enable their application for stable photovoltaic applications" in accordance with Chemistry of Materials and the Division of Inorganic Chemistry (DIC) of the American Chemical Society.
